FIELD: video decoding.
SUBSTANCE: group of inventions relates to video encoding and decoding technologies, more specifically, to extracting the output level in a multilevel encoded video stream. Proposed is a method for video decoding executed by at least one processor. The method includes a stage of identifying the maximum number of time sublevels permitted in the encoded video sequence referring to a video parameter set in a video parameter set (VPS) field and in a sequence parameter set (SPS) field, respectively. The encoded video sequence is then decoded based on the identified maximum number of time sublevels permitted in the encoded video sequence referring to a video parameter set.
EFFECT: reduced redundancy in the input video signal by means of compression.
